Oceans cover most of the Earth's surface, yet the underwater world remains a mystery to most people. This is why aquariums are such interesting attractions. They offer a glimpse of what goes on under the waves and at the bottom of lakes and rivers. In these unique exhibit halls, you can come face to face with huge marine mammals, vibrantly colored or unusually shaped fish, and habitats that are completely different from anything you can see on land. Case in point: this kelp forest at the Monterey Bay Aquarium.
If you want to come face to face with this often-hidden part of our planet, these world-class aquariums are a great place to start. (Text: Josh Lew)
